yeah i know they have a front diff. i was referring to the rwd drive sump if there was any diff between that and the rb25. think its prob safer to get one strait from the factory. pro eliminator looks like the go

cheers mate, ill stick with the 800's. what about the twin spray? worth the extra $100?

any1 else have any input? im just about to purchase the 800's but keep thinkin should i go to the 1000's to be safe lol also is there really much difference between the single and twin spray injectors? thanks again.

i did find one on here but its for a rb26 http://www.skylinesaustralia.com/forums/Hi...;hl=high+energy

they sound pretty trick. is the rb25 different to the rb26?

ooo link me!

hey hey, ive got a new set of cp forged pistons im going to drop in my built up 25/26 and was wondering if its worth gettin them ceramic coated or not. i know that it helps keep the heat up the top and is meant to work well but i have also heard cases of the coating chipping off which can score the bore and be very nasty. anyone else had good/bad experiences with this? quoted about $50 per piston, sound about right?? cheers.

lol 9ltrs is decent! sounds like ill go ahead with it then. where is the cheapest place to get one from. or possibly deal directly through high energy themselves?

hey guys, ive seen these high energy sumps for sale and was wondering if it really is worth it. if youve seen any of my other topics you would know im building up a 25/26 aiming for 500rwhp. ive done all the other oil control mods there is to do and my car will be seeing the track every now and then. is it worth the extra $800 or just stick with the standard option? thanks.

hey rob, yeah i was thinkin that but i dont wanna go too big to the point the injectors lose an efficient spray pattern. i was thinkin 800's but yeah could go 1000s. hmmm decisions decisions...

yeah slide is great for everything lol also does anyone know how much of a difference there is between using a 11mm rail and a std 10.5mm rail? cheers

thanks for the info! got a quote today, $180 for the crank and block. going to drop it off on friday and will be ready by monday. i would love to have the money to buy the best of the best lol by the time this engine is finished it will be owing me 18k, thats with me doin all the work, so i dont really wanna blow out anymore than i already have. an extra $180 is very affordable compared to say a new block and crank. thanks for all the input guys, adam.

nismoid, im hoping to get around 500rwhp out of it. ive got forged rods/pistons, type a cams and springs, lots of headwork and alot of money lol the list goes on of all the usual mods. that why i thought while it was out i might aswell do what i can do strengthen up the block and crank while im at it. its not 400rwkw but i dont like things near there limits, id rather overdo something the 1st time rather then not and be paying for it big time later on..

makes the metal stronger, read this http://www.heat.com.au/treat-cryotemp.html.

hey guys, ive just got my rb25 block and rb26 crank back from the machine shop and i was planning on getting it Cryotemp frozen. ive heard it works really well. milanco had that et pulsar that ran 11s and all it had was all the internals cryo'd. also my work mate had his 2lt turbo pinto block done and after 2 meets it had to be pulled down cause of a knock to find a cracked bore. could have just been a dodgey cast from factory though... has any1 else had good/bad experiences with cryotempering? thanks, adam.

ok cheers for that guys, some very helpfull info there. looks like ill get some sards as the price is pretty good on them

hey guys, im currently building my 25/26 and am using a greddy manifold and would like to convert from sidefeed to topfeed. im aiming for around the 500rwhp and will be using a hks rail, i noticed there is a 10.5mm (std) and a 11mm (oversize). is there really much diff and which brands make what size injectors? also there is the injector sizing issue, i was thinking around 700/750cc? i guess this would be enough to cope and wouldnt have to go to 1000cc's? what brands are good stuff? every1 tells me diff stories, i hear the 4 hole nismos are really good, then i know sard make good gear but ive heard dont use sard injectors any help on this would be apprectiated. am using a bosch 044 with surge tank and turbosmart fpr 800reg. thanks.

thanks bob! well i worked it out, if its 0 deck height it will come to 8.8:1 comp with a 1.5mm gasket. sooo i will have to see what the deck height comes to once its set up and then take it from there, thanks for the input guys, much appreciated!

yeah cheers guys, i know what effects cr and how to cc, done it couple times at work on the race car. just was looking for the lazy way out haha but na it is good to speak to some1 thats done this mod before for a few tips, looks like ill be doin it the hard way... and to cc a dome piston is pretty easy, u must cc the piston with it positioned exactly 1 inch down in the cylinder bore then fill the area above the piston with fluid, then subtract this volume from the calculated cylinder volume at 1 inch and u get the piston dome displacement in ccs. on a std engine does any1 know the cr difference in the diff thickness headgaskets though?

yeah might have too, ive got all the gear at work to cc everything so might have to get to it hmmm. yeah it does have 2mm more stroke from the crank having more throw and the piston pin height raised...

yeah all im getting at is the bottom end is basically a rb26, there could be a chance the deck height is slightly different... just assuming the deck height stays the same. then there is the head which is 2cc smaller compared to the rb26 head, so a slight increase of compression would occur but nothing the right size head gasket cant fix. so all in all i should be able to get the comp ratio pretty much back to standard right? the calculators ive tried cant be right because when i put specs in for a standard rb26 it gives a comp ratio of 6.7:1 which is waay off. ive seen a neo motor with a 26 crank running a 1mm head gasket, didnt give me comp ratio but apparently was good if anyone has done this before any info would be handy as the motor is at the machine shop atm, cheers guys.

tired to work it out with the cr calculator but wasnt right at all, if you can give me a hand to work this one out bob it would be greatly appreciated, thanks again.

87mm bore. how will it affect it if the crank compensates for the different piston pin height? the squish area should be exactly the same as using rb25 crank and pistons, correct? cheers.

hey guys, ive got a rb25det which is in the build and im getting a tomei head gasket but cant find what compression relates to what size, 1.0mm, 1.2mm, 1.5mm and 1.8mm. if any1 could help that would be great. note i am also using a rb26 crank and rb26 forged pistons though this shouldnt affect the outcome. cheers.

hey mate will you seperate the manifold? if so im interested, pm me when ya back, cheers.
